It is a high-strength hard aluminum that can undergo heat treatment and strengthening. It has moderate plasticity under annealing, hard quenching, and hot conditions, and good spot welding weldability. When using gas welding and argon arc welding, aluminum pipes tend to form intergranular cracks; After quenching and cold work hardening, the machinability of aluminum pipes is still good, but it is poor in the annealed state. The corrosion resistance is not high, and anodizing and painting methods or adding an aluminum coating on the surface are often used to improve the corrosion resistance. It can also be used as a mold material.
